Ground-based Observations
by Scripps Institution of
Oceanography (SIO)
|
Surface observations from a variety of sites will
support this
research. The locations of these sites are shown in the figure below.
The ABC
(Atmospheric Brown Cloud) observatories are shown by white stars (5
sites) and are operated by the ABC project (Ramanthan, co-chief
scientist) with NOAA funding in collaboration with regional scientists
and agencies.
On the western side, the Bashang site of inner Mongolia
(in collaboration with U. of Peking) will be able to sample the dust
and its radiative forcing before it is mixed with pollution over
eastern Asia. The Gosan site (an ABC super site maintained by
Seoul
Natl Univ.) will sample the polluted dust as it exits Asia into the
Pacific. The Okinawa ABC site in Japan (maintained by Univ Of Tokyo)
will capture the southern flank of the dust. In the mid Pacific,
the
Midway site (maintained by Scripps) will sample the southern flank of
the plume. The Trinidad Head (California; maintained by
NOAA-Boulder)
site will sample the dust and BC reaching the coastal surface. All of
these ABC sites will have aerosol chemical sampling and radiative flux
measurements. The Bashang (China), the Gosan (Korea) and Okinawa
(Japan) site will also have Lidar to estimate the vertical extent of
the plume. A description of the instrumentation for the ground
based sites is provided in table below
